A treatment system for liquid ammonia leakage

Abstract

The invention relates to a processing system for liquid ammonia leakage. The processing system comprises a liquid ammonia storing tank, the exterior of the liquid ammonia storing tank is covered witha protection cover, a liquid ammonia leakage sensor is arranged inside the protection cover, a sucking device is fixedly connected to the top of the interior of the protection cover and is connected with an absorbing device located outside the liquid ammonia storing tank through a first pipe, an induced draft fan is arranged on the first pipe, the absorbing device comprises a shell, a first coveris arranged at the bottom of the interior of the shell and is in an inversed hopper shape, and a first through hole is formed in the upper end of the first cover. The processing system has the beneficial effects that the liquid ammonia leakage sensor will detect that liquid ammonia exists in the protection cover, signals can be transmitted by the liquid ammonia leakage sensor to the control system, the control system controls the induced draft fan to work, ammonia at the top of the interior of the protection cover is absorbed into the sucking device through evenly-arranged sucking covers, it can be guaranteed that leaked ammonia can be effectively absorbed, and dangerousness is reduced.

Description

technical field [0001] The invention relates to the technical field of hazardous gas leakage treatment, in particular to a treatment system for liquid ammonia leakage. Background technique [0002] Liquid ammonia is used in the production of compound fertilizers by the amino acid method. There is a danger of leakage of liquid ammonia during storage and use. Once it leaks, not only will there be economic losses, but it will also threaten personal safety and cause safety and environmental accidents. Therefore, it is necessary to carry out safety alarm control on the liquid ammonia storage device. The prior art generally adopts the method of installing an ammonia gas leakage alarm and a spray system at the liquid ammonia storage site, and the ammonia gas leakage detector will send an alarm after detecting the ammonia gas leakage After receiving the alarm signal, the on-site staff will start the sprinkler system to spray water and dissolve the leaked ammonia gas. But, the liqu...

AI Technical Summary

Problems solved by technology

However, the liquid ammonia leakage alarm processing device of the prior art has the following disadvantages: the one is that after the ammonia gas leaks, the on-site staff needs to be remotely controlled to spray, the response is slow, and the treatment is not timely

The 2nd, the nozzle of the spraying device of the spraying system of the prior art is arranged at the position near the top of the liquid ammonia storage tank, because the specific gravity of ammonia gas is smaller than that of air, the above device cannot effectively process the ammonia gas floating to the top, and some existing Some technologies use the method of installing an exhaust fan in the room where the liquid ammonia is stored, but this method only exhausts the ammonia gas from the storage room to the outside, and does not fundamentally solve the problem of ammonia gas treatment
